Answer:
4c
Explanation:
![(-60*c^(7) )/(-15*c^(4))](https://img.qammunity.org/2022/formulas/mathematics/college/j1d6myiryzactujyzxw46r0lgyrrskm7ba.png)
Let's reduce the numbers and then we'll reduce exponents of c.
![(-60)/(-15)=4](https://img.qammunity.org/2022/formulas/mathematics/college/dwql6p4bpo5amelcweweyl2te4rvchd979.png)
Using exponent rules, we simply subtract the exponent from the top and the exponent from the bottom.
7 - 6 = 1
The exponent of c is 1, which is just c
Combining this, we get 4c
